.SH NAME

spmvtest1 \- SpMV kernel benchmark of one dimensional Laplacian

.SH SYNOPSIS

\fBspmvtest1\fR \fIn iter\fR [\fImatrix_type\fR]

.SH DESCRIPTION

This program computes the matrix-vector multiply of a discretized 
one dimensional Laplacian of size n using the three point 
central difference scheme, and a vector (1, ..., 1)^T. The FLOPS 
performance is measured as the average of \fIiter\fR iterations. 
If necessary, one of the following values can be specified by \fImatrix_type\fR:
.IP "0"
Measure the performance for the available matrix storage formats
.IP "1-11"
The number of the matrix storage format
.PP
The value \fIn\fR represents the number of the grid points.
See Lis User Guide for more information.

.SH EXIT STATUS

The following exit values are returned:
.IP "0"
The process is normally terminated
.IP "unspecified"
An error occurred
